Background: Mandibular fractures are among the most common maxillofacial fractures which affect talking and
swallowing ability. Aim: To evaluate the effect of implementing teaching program on patient outcomes suffering from
mandibular fracture. Design: Quasi-experimental research design was used in this study. Setting: The current study was
conducted at Plastic & Reconstructive Burn Center and Mansoura university hospital. Sample: A purposive sample of
80 conscious adult patients with mandibular fracture was recruited in the study. Tools of the study: Three tools were
used to collect the data: Tool I: Interview Questionnaire sheet: divided into 3 parts: Part 1: Demographic data, Part 2:
Patient's medical health history, Part3: Patient's knowledge regarding mandibular fracture questionnaire. Tool II: Patient
assessment sheet. Tool III: Tempo mandibular dysfunction (TMD) Disability Index Questionnaire. Result: The results
of this study revealed that there were highly statistically significant differences (P<0.001) in level of knowledge at pretest,
post-test and follow up test, over all complication were decreased in study group in post-test and follow up test
compared to control group. Recommendation: Provide adequate knowledge about nutrition, oral care and jaw exercise
to mandibular fracture patient to help them reach full recovery.
